VTo all whom itmay conce/rn; y Beit known that I, ALVIN WARREN, tot* Swan; ton, in the county of Lucas and State of Ohio, have `invented a newand valuable Improvement in r Cooking-Stoves; and I 4do-,l1ereby declare that the "following is a `full, clear, andexact description oi the construction and operation of thesame, reference being had tothe annexed ,drawing making a part'of this specification, and to the letters andrtigures of reference `markedthereon;

It also consists in providing. a stove so constructed with" a dryingchamber, located below the oven and behind the {irc-box. i

- l'.Ifh Schedule referred to in these Letters Patent and making part of Athe same.

G represents the smoke-line, and- H, the oven, elevated on top of the stove, behind it, and provided with surrounding air-chambers, divided, by partitions, into dues, z, corresponding with those in the stove, with which they respectively communicate through-the passages h 1i. 1

'lhe side ues ofthe oven 'communicate withfthe side lines of the stove at the back of the oven only.

The middle due communicates at both the front and back of the oven. 'Ihe partitions dividing theovemues terminate, as will be observed in lig. 1, at a` sufficient distance above the top of the stove to vallow the heated currents to pass from one to the other.

I is a damper for directing the hot currents passing through the middle line.

J are perforated oven-plates.

'K are ventilating-tubes. L are boiler-holes.

The ovenis properly heated by turning the triplewinged damper down and letting the heated currents ow back and around the oven, heating the outer portions rstthence returning through the middle line, and ascending the smoke-flue.

Until the proper temperature is reached the damper I should be turned up. llhe products of combustion ing h', -and ont through the smoke-pipe.

When the fire is thoroughly kindled the damper I may be turned to close the opening hf, and the pro-- ducts of combustion will then be directed back through the Vmiddle/flue 2, and then forward through the mid-4 die flue F, and out at the smoke-pipe.

triple tlnes F FfF, the triple-winged damper F', and the drying-chamber E, as specified.
